Abstract: This pneumatic tire is provided with: a run flat reinforcing layer 19 disposed in the width direction inside of a carcass layer 13; and a second filler 20 disposed between a rewinding part of the carcass layer 13 and a rim cushion rubber 17. In addition, a point P on a tire outer circumferential surface at a 150% position of a rim flange height from a measurement point of the rim diameter of a specified rim is defined, and a perpendicular line L is defined which is drawn from point P to the tire inner circumferential surface. At this point, a rubber gauge G1 of the run flat reinforcing layer 19 on the perpendicular line L, and a rubber gauge G2 in a region from the rewinding part of the carcass layer 13 to the tire outer surface have the relationship of 0<G1/G2≤0.65.
